X299 features and RAM

[BrandonT]

Looks like my 3570k is finally getting replaced this summer, most likely with the 7820X. I'm a bit out of the loop on the state of the art, so could use some advice. My machine will do a lot of video encoding, mostly Handbrake, and some gaming on 2560x1440 monitor. I will probably not overclock this machine, if I do it will be conservative.

What RAM specs should I be looking at? I'm guessing quad channel is better than dual, all things equal? What's this "ranking" I'm reading about?

How is Thunderbolt and USB 3.1 support going to be on X299?

Any other issues I should consider with X299?

Could really use some advice on my questions above...

BTW looking at RAM I must get ones that say "X299"?

Is cost a consideration? While X299 should be faster, if cost is something you value, a Ryzen system would be much better bang for the buck for what you're doing.
